Bad customer service

These people are the worst. I app**** on line for credit. Was pre approved and went to the store to proceed with application. Next thing they hand me over some one who knows nothing about credit to assist me. Lady puts my name on the SURNAME column and surname on the NAME column. Then sends the application to Head Office. The very same day at 5pm she calls me to say they want an accountant letter, I ask what is that? She doesn't even know. How do you pick up the phone and call a customer without full information to start off with. Then I call the store next day find the supervisor who also doesn't but at least finds out and tells me that names were switched and I must come to the store. I tell her I will not afford to loose time again over a mistake that is not mine. They then start a new application with a new reference number. I follow up with the call center and find out that she didn't scan the back of my ID. She calls me an hour later and lies that the ID didn't scan properly so I should come. How do you ask someone with no idea what to do, to actually assist your valued customer or potential customer. Now I must visit the store tp get an ID Scanned.
